That's not true. The threshold for Dark Force/Berserk functions very different after the Big Bang patch. Before the Big Bang patch, Berserk requires being BELOW a certain percent of HP. It is a huge pain to keep it active. After the Big Bang patch, Berserk requires being ABOVE a certain percentage of HP. This recent change now makes it even easier to stay above the HP threshold, making the buff almost always active.

Any half-decent Dark Knight could handle the 50% or less. In exchange for "easier" training Berserk is now crap.
